Je. Beget et Rj. Motyka, NEW DATES ON LATE PLEISTOCENE DACITIC TEPHRA FROM THE MOUNT-EDGECUMBEVOLCANIC FIELD, SOUTHEASTERN ALASKA, Quaternary research, 49(1), 1998, pp. 123-125
New radiocarbon dates on charcoal incorporated in proximal airfall dep
osits indicate the largest late Pleistocene eruption from the Mt. Edge
cumbe volcanic field in Southeast Alaska occurred ca. 11,250 +/- 50 C-
14 yr B.P. The more precise dating of the principal Edgecumbe tephra l
ayer greatly improves its utility as a tephrochronologic marker horizo
n in southeastern Alaska. (C) 1998 University of Washington.
